ToaZZ whom; t Mag/' ccinoern: -i i Be it known that I1, Louis LUMIERE, aciti' zen of the French Republic, and residing .at

262 Cours Gambetta,.Lyon, France, have-in'- vented certain new and useful lImprove-- ments in and Relating to Talking-Machines,

f: This specification relates. to improvementsv in talking n'xachines,yparticularly' vto that type .of talking machine illustrated-11n andPatent of the United States, No.1986f477,

dated March 14,1911, special-.reference bel; ing had. to theconstruction, illustrated' in- Figure 1 0 of said application. Myvinvent-ion" has for itsV object,

stylus With-the diaphragrrn?.

y A further objfct of construct. the connection kbetween thestylus 2 andthe diaphragm, particularlysfvslien''dia phragms of large diameter; are,employ/,edi4

fully without beingfzsub'jec'ted; tot any :torfV sional ,orother-:.strains, due tothe'fact' that,

, the diaphragm is attached to.. -a stylus bar,l

such as are illustrated-in m above! nnenf` tioned applicatiomtha-t thesaiddiaphrag'ms are' permitted 'tol and'4 will. vibrate freely andattachment ofthe stylus with the diaphragm Wil not vibrate any othermanner-than in :a line substantially i1ormal*to the aplane ofthediaphragm. j.. ff? 1 In carrying out my invention, 'I make theconnection between;l the stylus and ythe i diaj phragminsuchfa' manner'-that the 'dia-, phragrn is :locatedl substantiallyA parallelwith a diskrecord?, and I" provide such a con- 1 nection4 between fthe, diaphragmo, andiy the] pointof thelstylius that by simply turning thesoundbQXQthrough a right angle in the .plane of #thediaphragm,l the'`sound boxy maybe used with.' both of the 'common types' ofn diskrecords; 'thatff is; to' say,` withv disk recordsy in ,Which the. soundAWaves are .re-
